Answer 1

Explicație pas cu pas:

$\frac{10}{ \sqrt{2} } = \frac{10 \sqrt{2} }{ \sqrt{2} \times \sqrt{2} } = \frac{10 \sqrt{2} }{2} = 5 \sqrt{2}$

$\frac{15}{ \sqrt{3} } = \frac{15 \sqrt{3} }{ \sqrt{3} \times \sqrt{3}} = \frac{15 \sqrt{3} }{3} = 5 \sqrt{3}$

$\frac{ \sqrt{7} }{ \sqrt{5} } = \frac{ \sqrt{7} \times \sqrt{5} }{ \sqrt{5} \times \sqrt{5} } = \frac{ \sqrt{35} }{5}$

$\frac{ \sqrt{3} }{7 \sqrt{2} } = \frac{ \sqrt{3} \times \sqrt{2} }{7 \sqrt{2} \times \sqrt{2} } = \frac{ \sqrt{6} }{14}$

$\frac{ \sqrt{5} }{ \sqrt{18} } = \frac{ \sqrt{5} }{ 3\sqrt{2} } = \frac{ \sqrt{5} \times \sqrt{2} }{ 3\sqrt{2} \times \sqrt{2}} = \frac{ \sqrt{10} }{6}$

$\frac{3 \sqrt{5} }{ \sqrt{12} } = \frac{3 \sqrt{5} }{2 \sqrt{3} } = \frac{3 \sqrt{5} \times \sqrt{3} }{2 \sqrt{3} \times \sqrt{3} } = \frac{3 \sqrt{15}}{2 \times 3} = \frac{\sqrt{15}}{2}$

$\frac{8 \sqrt{3} }{ \sqrt{32} } = \frac{8 \sqrt{3} }{4 \sqrt{2} } = \frac{2 \sqrt{3} \times \sqrt{2} }{\sqrt{2} \times \sqrt{2} } = \frac{2 \sqrt{6} }{2} = \sqrt{6}$

$\frac{5 \sqrt{3} }{ \sqrt{15} } = \frac{5 \sqrt{3} }{ \sqrt{5} \times \sqrt{3} } = \frac{5}{ \sqrt{5} } = \frac{5 \sqrt{5} }{ \sqrt{5} \times \sqrt{5}} = \frac{5 \sqrt{5} }{5} = \sqrt{5}$
